Welcome 'home', Doğan!
I saw that you also introduced yourself in the Turkish Team section. It has been quiet there for a while, so your intro may inspire some folks to 'reactivate'.

In the meantime, is there a particular project that you're interested in focusing on? The Turkish Team section includes a "Published Translations" board that will show you all of the fully completed projects, and a "Current Projects" board that contains everything that has been started but is not yet completed, and is awaiting someone to come along and push them further.

The full list of everything within our care that is ready for translation across all Language Teams can be found in the global "Open for Translation" section, which is separated into video-based (dotSUB) and text-based (Pootle) projects.
